Chrysanthemum plant named ‘Sywan Pur’

ABSTRACT

A new  Chrysanthemum  plant named ‘Sywan Pur’ particularly distinguished by the bold red-purple inflorescence color, medium green foliage, rounded and mounded plant habit, and a natural flowering season response that is about early October.

Latin name of the genus and species of the plant claimed: Chrysanthemum×morifolium.

Varietal denomination: ‘Sywan Pur’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Chrysanthemum, botanically known as Chrysanthemum×morifolium, and hereinafter referred to by the variety name ‘Sywan Pur’.

‘Sywan Pur’ is a product of a planned breeding program. The new cultivar has bold red-purple inflorescence color, medium green foliage, rounded and mounded plant habit, and a natural flowering season response that is about early October.

‘Sywan Pur’ originates as a natural whole plant mutation of ‘Yowanda’, U.S. Plant Pat. No. 20,210. Sywan Pur' was discovered and selected by the inventor as a single flowering plant within a population of the parent cultivar in a controlled breeding program in Alva, Fla. in November 2007. The parent cultivar ‘Yowanda’ has larger and lighter purple inflorescences and a natural flowering season response that is 3-4 days faster.

The first act of asexual reproduction of ‘Sywan Pur’ was accomplished when vegetative cuttings were propagated from the initial selection in December 2007 in a controlled environment in Alva, Fla.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in December 2007, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Sywan Pur’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Sywan Pur’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar was applied for in Canada on Apr. 9, 2010 (No. 10-6934). ‘Sywan Pur’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Chrysanthemum as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Sywan Pur’ with colors being as true as possible with an illustration of this type.

The photographic drawing shows a flowering potted plant of the new variety.

DETAILED BOTANICAL DESCRIPTION

The plant used for the photographs was about 16 weeks old grown in Monroeville, N.J. in an outdoor trial. One rooted cuttings grown in a nine inch pot with no terminal pinching of the apices. The photograph was taken in mid October 2010 in New Jersey.

The plant descriptions and measurements were taken in Gilroy, Calif. in May 2010 under natural light. Plants were grown under conditions which approximate those generally used for potted chrysanthemum trials in a greenhouse. These plants used in the descriptions were about 10 weeks old.
